A submersible heater with a preset thermostat, for the water section of a paludarium or a shallow aquatic habitat. Preset means no dial to set and no dial to get wrong — useful if you are heating a small volume where a miscalibrated adjustable heater does damage quickly. It shuts off automatically if it is lifted out of the water.
Sizes
- 25W — for small water sections, around 26 litres
- 100W — for larger water volumes
Features
- Preset thermostat — holds around 26°C without adjustment.
- Automatic shut-off out of water — protects the element if the level drops.
- Suction cup mounting — included.
Using it
- Fully submerge it before plugging it in — running a heater dry will destroy it.
- Allow one to three hours to reach temperature before judging it.
- Position it near the filter outflow so heated water circulates rather than stratifying.
- Use a thermometer to confirm the actual water temperature.
Pairs with the Paludarium Filter. More in Reptile Habitat Accessories.
